The MOUDI Impactor is designed to collect size-fractionated particle samples in four equal geometrical intervals per decade of particle size for mass or chemical analyses. The nominal cut-size diameters for these impactors start at 10 µm and end at 10 nm for the current 125R model. The use of aluminium foils/PTFE filters of required pore size and diameter enables gravimetric mass collection to give size segregated mass concentrations and facilitate the use of foils/filters for further chemical analysis.

Main Features:

Instrument Made : TSI MOUDI 125R.

1. Reliable internal impaction plate rotation provides nearly uniform particle deposits for better quantitative chemical analysis.

2. Micro-orifice nozzle plates designed for low flow resistance and reduced particle bounce and re-entrainment.

3. Up to 13 impactor stages with nominal cut points between 10 nm and 10 µm, plus a final filter.

4. Low inter-stage losses.

5. Sharp cut-off size characteristicsSharp cut-off size characteristics.
